Ādam ibn Abī Iyās reported to us, he said: Ibn Abī Dhi’b reported to us, from al-Zuhrī, from ‘Urwah,
from ‘Ā’ishah bint Abī Bakr (may Allāh be content with her), who said: I and the Prophet Muhammad ﷺ used to perform Ghusl together from a single vessel, which was called a Faraq [a container that held approximately eight litres of water, as mentioned by al-‘Aynī].
حَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنِ الزُّهْرِيِّ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ،
قَالَتْ كُنْتُ أَغْتَسِلُ أَنَا وَالنَّبِيُّ، صلى الله عليه وسلم مِنْ إِنَاءٍ وَاحِدٍ مِنْ قَدَحٍ يُقَالُ لَهُ الْفَرَقُ.
